Clutch-cover assembly - has edges of annular spring-plate supported on opposite sides by pressure plate and diaphragm spring and at points offset sideways when disengaged

摘要

The inner and outer edges of the spring plate (16) bear on opposite sides against the pressure plate (12). The diaphragm spring (11) bear along lines offset sideways in the disengaged position, these moving closer together on engagement. The end face of the pressure plate furthest from its lining contains an annular channel (50), whose bottom curves away from one of the contact lines. ADVANTAGE - Gives parabolic and gently-sloping characteristic damping curve.
